Abstract

The photocurrent quantum yields of para-substituted tetraphenylporphyrins were found to be increased by electron-donating groups. Semi-logarithmic plots of the quantum yields vs. the half-wave potentials for the first ring oxidations of the porphyrins or the Hammett σ of substituents yielded a linear relationship.
